Wright Brothers Crank Set

If everything is equal–crank arm hole and drive pin...than a picture is worth a 1000 words!






No two patterns are the same! The 3 large mushrooms on "B" are slightly indented on their tops offering more of a kidney bean shape. Plus, the bottoms of the 3 large mushrooms on both "B&C" are diminished.

Lovely chainring and one of my favorites....The number 3 is significant in many ways, and particularly in terms of mathematics. The 3 skull-head cutouts as well as the six imperfect triangles and the two fangs in each of the kidney bean ovals really bumps up the cool factor.

Very interesting..........I like the work on the graphics Carlton although, the two bikes are opposite the picture of the chainring in the catalog and align with “C” ? The number of teeth on “C” is the same as the ring in the catalog and the two bikes. I wonder if it’s just how the graphics were done in the catalog?

Just measured a GWM “crown” sprocket; the drive pin hole is about 1+5/8” from the shaft hole, center-to-center. [And the shaft hole is fairly tight on 15/16” minus a few hairs].
I believe that the different sizes are only similar; 26 tooth being about 18% larger than the 22 tooth, in one dimension; and about 40% larger in area. One was not a scaled up or down version of the other.
